Optima Mid and Brushless

[Bagman]

Just a quick question for those in the know. How many turn brushless motor should you go to on a bog standard Optima Mid?

Cheers in advance

Ooooh, oohh!!! Did you get any answers elsewhere, or figure it out ??? I'm wondering exactly the same thing now--- How many turns motor should I get if I go brushless with my Optima Mid?!?!

Also-- Can I use NiCd's for now with, say a Mamba ESC and motor and then hop over to LiPo?? Would the NiCd's just have really short run times?

Any input greatly appreciated!!!

Missed this first time round!

I've run one with a 10.5 in it for 6 meetings and wouldn't want to use anything more powerful as I'm not sure that the belt would cope.
(that's with lipo too)

I ran a 13.5 in mine indoors and I DOMINATED

Would I be safe with a 13.5 in a chain drive Optima too?

Only cause you cut half the track against me. Still may be an idea to tension the rear belt if your using as they may strip.

I ran my LWB Mid hard in Oz with a 10.5 system and LiPo's (see my avatar ) - it survived but now hasa B4 slipper fitted to hopefully prolong the life of the transmission.

Just like to point out the Mid doesn't have a rear belt although the idler gear is a weak point in the drivetrain.
